Abstract
Negative pressure wound therapy (NPWT) or vacuum-assisted closure (VAC) of wounds is a treatment modality that consists of applying sub-atmospheric, or negative, pressure to a wound resulting in wound protection, drainage and accelerated wound healing. NPWT systems are constructed by the use of commercial or improvised systems; the wound is packed with open cell polyurethane foam or gauze, covered with adhesive drape and connected with tubing to an adjustable suction device. Recently, more portable, single-use systems have been developed, that make them more versatile for use, particularly in veterinary patients.
